“There is a growing effort to identify agents that can upregulate PD-L1 to increase the potential number of patients that can be treated with immune checkpoint blockade,” said Dr. Hofmeister. “The data in this poster clearly demonstrate an increase in viral infection and viral replication, as well as pelareorep-dependent PD-L1 increased expression on the surface of myeloma cells, among patients undergoing treatment with pelareorep in combination with carfilzomib.”

Highlights from the Poster:

Responses include:

Three very good partial responses (at least 90% reduction in monoclonal protein)

Three minimal responses (between 25% and 50% response to a drug or regimen in a clinical trial

Three stable disease

In patients receiving pelareorep with a clinical response, there was simultaneous CD8, PD-L1, and NK cell response, as well as activated caspase-3 expression

In patients treated with pelareorep, PD-L1 expression incrased significantly more in patients with clinical response

“This presentation adds to the growing body of clinical evidence that pelareorep can boost PD-L1 expression and has the potential to be a backbone for immune checkpoint inhibition,” said Dr. Matt Coffey, President and Chief Executive Officer of Oncolytics Biotech. “We appreciate the continued support of Dr. Hofmeister and look forward to collecting additional data from his subsequent study combining pelareorep with Bristol Myers Squibb’s immune checkpoint inhibitor, Opdivo, which should begin enrollment before the end of the year.”

About PelareorepPelareorep is a non-pathogenic, proprietary isolate of the unmodified reovirus: a first-in-class intravenously delivered immuno-oncolytic virus for the treatment of solid tumors and hematological malignancies. The compound induces selective tumor lysis and promotes an inflamed tumor phenotype through innate and adaptive immune responses to treat a variety of cancers and has been demonstrated to be able to escape neutralizing antibodies found in patients.

About Oncolytics Biotech Inc.Oncolytics is a biotechnology company developing pelareorep, an intravenously delivered immuno-oncolytic virus. The compound induces selective tumor lysis and promotes an inflamed tumor phenotype -- turning "cold" tumors "hot" -- through innate and adaptive immune responses to treat a variety of cancers. Oncolytics' clinical development program emphasizes three pillars: chemotherapy combinations to trigger selective tumor lysis and immunotherapy and immune modulator (IMiD) combinations to produce innate and adaptive immune responses. Oncolytics is currently conducting and planning additional studies in conjunction with checkpoint inhibitors and targeted and IMiD therapies in solid and hematological malignancies, as it prepares for a phase 3 registration study in metastatic breast cancer.
